AnswerStacy,
There is a glide 137513300 on the front of the drum that if it wears out it will cause the unit to have a vibration. You will also want to check to make sure that the idler pulley is not jamming up causing the issue.

AnswerHello Mary,
A squeaking sound is usually caused by the rear bearing assembly 5303281153. The idler pulley can cause a noise but it usually isn't a squeaking noise because the belt will be sliding on the pulley that isn't turning.

AnswerHello Bob, Generally we would not change parts just to change them but since you would be in the unit it would not be a bad idea to check to see if there is any wear. If there is wear replace parts 131863007 Idler arm and 131601000 Idler Spring. I would recommend changing spring at the same time you change Arm

AnswerHello Bruce. Check and see if the front seal 134440200 is bad in the unit. If it is good, you will need to check and see if the blower wheel is loose or bad and if it is clogged with lint. If so, it will cause the issues you are having with the unit.

AnswerHello Barbara. Based on the information, on this model, it is best to replace the rear bearing kit 5303281153, front glide 5303937139, and if needed, idler pulley 131863007. Usually the noise if the rear bearing and the front glide more than the idler pulley.

AnswerHello Jer. Yes, the pulley moves back and forth. If the belt is not on the pulley, you can slide it off the idler assembly 131863007. The pulley is mounted correctly to the assembly. Hope this helps.
